About this event

In autumn, Chamrousse becomes the backdrop for the Trail des Lacs de Chamrousse-Belledonne (TLCB), a flagship race of the region offering four routes — Trail Sportif (23.2 km), Trail Classique (13 km), Trail Découverte (4.5 km), and Trail Jeunes (about 1.3 km). Run along the trails around the spectacular lakes (Achard, Roberts, Pourettes, Vallons) and climb toward the Alpine summits of Isère. A varied trail experience in a unique mountainous and forested setting.

Renowned for its ski resort which also hosted the 1968 Winter Olympics, the Chamrousse is also and above all a land of trail! 🏃‍♂️ Indeed, amid the lakes 🌅 and the Alpine peaks ❄️, this commune in the Isère, in the region Auvergne-Rhône-Alpes, is the place to be for the awesome runner you are! 🤝 And that’s perfect, because today we’re taking you to one of the region’s most beautiful races: we’re talking, of course, about the Trail des Lacs de Chamrousse-Belledonne (TLCB)! 😉

Organized at the end of September, this trail will let you discover Chamrousse in its autumn version 🍂. After ski season, the town indeed transforms into a beautiful small village in the middle of the mountains ⛰️ and the forest 🌲 where all kinds of outdoor activities can be enjoyed: hiking 🥾, MTB 🚲, climbing 🧗🏻‍♂️, … But above all you’ll find incredible trail routes, each more technical than the last 🏃‍♂️.

The Trail des Lacs de Chamrousse-Belledonne offers several extraordinary routes! 🗺️ This year, four routes are available: the "Trail Sportif" (23.2 km - 1 700 mD+), the "Trail Classique" (13 km – 810 mD+), the "Trail Découverte" (4.5 km – 350 mD+) and the "Trail Jeunes" (about 1.3 km). This trail will take you to discover some of the region’s most beautiful water spots: the fabulous Lac Achard, the Lacs Roberts but also the Lac des Pourettes or the Lac des Vallons… 🏞️ You’ll see, the Trail des Lacs de Chamrousse-Belledonne, is above all a walk to meet the region’s most beautiful lakes 🐟.

There are those who love the mountains, and those who prefer the sea during summer holidays 🌞, but know that it’s entirely possible to enjoy both. By taking part in the Trail des Lacs de Chamrousse-Belledonne, you’ll discover some of the region’s most beautiful summits of Isère... But you’ll also get to explore several incredible water spots like the Lacs Roberts. A quirky name for a lake, we grant you! 😂 Yet, located at 1 998 meters above sea level, this group of four lakes is famous for its uniquely blue color! 😎 These four lakes are also home to countless rainbow trout and nine-spotted blue butterflies 🐟. Ready for a fishing session mid-trail? 🎣 You’ll also discover the Lac Achard and its breathtaking view of the Taillefer massif 🏔️. Don’t hesitate to pause a moment to enjoy the silence 🤫, take in the view, the centuries-old pines, the sedums (crassulacean plants with pink flowers… Thanks Wikipedia 😅), the cobwebs… 🕸️

Finally, you can make this race a chance to discover Chamroussethis small village at the southern edge of the Belledonne range! Just 30 km south of Grenoble, Chamrousse is a tiny mountain village of about 470 inhabitants in the Belledonne massif 📍. The resort is nestled in a lush forest, offering a spectacular view of Grenoble and its valley… 😲 A true haven to focus on the race and reconnect with the nature 🌿. The village offers stunning landscapes: on the horizon, green mountains, pines, and that azure-blue water reflecting the sky! 🥰 If you’re lucky, you might even spot ibex, chamois, deer, red foxes, wild boar, and even some marmots! 🐐

And, what do you do after the race? If you’ve still got energy, you can try the rock climbing route 🧗🏻‍♂️ or rent a paddle at Roche Lake! 🏄‍♂️ You can stroll around the largest lake in the resort and enjoy a mind-blowing panorama 🤩, with an amazing view of the surrounding ranges. Finally, we recommend tasting some of the region’s specialties like gratin dauphinois or Saint-Félicien, paired with a good glass of wine or Chartreuse 🍷.

So, are we heading to the mountains this fall? 😅
